D Printed Metallized Plastic Waveguides for Microwave Components

摘要

This paper investigates the design and fabrication of 3D printed waveguides and their application for the design of microwave passive components. This includes a simple waveguide structure, a bandpass filter, waveguide power splitter, a leaky wave antenna and a slot antenna array. A Lego-like approach is used to assemble different 3D printed sub-sections after metal coating. Details of modeling, fabrication and measurement results are presented, and simulation and measured results match closely.
